We crossed at Anzalduas,Tx they x-rayed the unit one new tv laying on the couch they never wen't inside, one tv should be OK two tv's might be a problem at the Sonoyita check point, that is the worst customs inspection place, all they want is the money for the mordida or they confiscate what ever they fancy.
Leave one tv at home, and do not take any meat, that will be confiscated.
